We call this an affine combination .

Affine combinations The affine combination of two points is defined to be the point . The point Q divides the segment connecting the two original points in a ratio proportional to the two coefficients. As long as the coefficients still sum to 1, this can be generalized to an arbitrary number of points:Think of the affine combination as a linear combination of position vectors, which we want to specify a point. Now, a position vector has two parts; a base vector to whatever point we're calling zero, and a displacement from that. Suppose you have coordinates based on the street grid numbers in a city - the vector says to go to the "zero point ...14.1: Affine transformations. Affine geometry studies the so-called incidence structure of the Euclidean plane. The incidence structure sees only which points lie on which lines and nothing else; it does not directly see distances, angle measures, and many other things. A bijection from the Euclidean plane to itself is called affine ...
In general, an affine combination is a linear combination for which the sum of the coefficients is 1 1. Here, this serves to keep the resulting point on the z = 1 z = 1 plane. On the projective plane, an affine combination isn’t enough to capture all of the points on a line. If both p p and q q are finite, (1 − λ)p + λq ( 1 − λ) p + λ ...Convex Optimization - Convex Set. Let S ⊆ Rn S ⊆ R n A set S is said to be convex if the line segment joining any two points of the set S also belongs to the S, i.e., if x1,x2 ∈ S x 1, x 2 ∈ S, then λx1 +(1 − λ)x2 ∈ S λ x 1 + ( 1 − λ) x 2 ∈ S where λ ∈ (0, 1) λ ∈ ( 0, 1). The union of two convex sets may or may not be ...Affine and convex combinations Note that we seem to have added points together, which we said was illegal, but as long as they have coefficients that sum to one, it's ok.

In other words, an affine subspace is a set a + U = {a + u |u ∈ U} a + U = { a + u | u ∈ U } for some subspace U U. Notice if you take two elements in a + U a + U say a + u a + u and a + v a + v, then their difference lies in U U: (a + u) − (a + v) = u − v ∈ U ( a + u) − ( a + v) = u − v ∈ U. [Your author's definition is almost ... ….

The convex combination of filtered-x affine projection (CFxAP) algorithm is a combination of two ANC systems with different step sizes . The CFxAP algorithm can greatly improve the noise reduction performance and convergence speed of the ANC system.Convex Sets Definition. A convex set is a collection of points in which the line AB connecting any two points A, B in the set lies completely within the set. In other words, A subset S of E n is considered to be convex if any linear combination θx 1 + (1 − θ)x 2, (0 ≤ θ ≤ 1) is also included in S for all pairs of x 1, x 2 ∈ S.

However, there is a problem with the naive approach involving a coordinate system, as we saw in Section 2.1. Since this problem is the reason for introducing affine combinations, at the risk 23 2.4.affine combination (plural affine combinations) (linear algebra) A linear combination (of vectors in Euclidean space) in which the coefficients all add up to one.

In this work, we propose a new adaptive equalizer based on a pseudo affine projection technique to equalize the channel. The proposed equalizer uses multi-pseudo affine projections of the channel output to update the filter equalizer.
